HEADLIGHT CASING.

Application filed August 11,- 1922. serial No. 581,081.

I '0 all whom it may concern:

Be it knownthat I, CHARLES W. DAKE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois. have invented a certain new and useful Improvement in Headlight Casings, of

, which the following is a specification.

This invention relates to light casings and particularly to a casmg for locomotive headlights. It has for one object to provide means whereby the headlight may be readily adjusted so that the beam maybe directedat the point desired. Another object is to provide a safety latch whereby the door of the casing may be readily locked by merely shutting the same. but which cannot be accidentally opened. Other objects will appear from time to time throughout the specification and claims.

My invention is illustrated more or less diagrammatically in the accompanying drawings, wherein:

Figure 1 is a side elevation of the headlight casing;

Figure 2 is an elevation looklng from the rear' Fig. 3 is a partial vertical cross section on an enlarged scale taken on line 3-3 of Figure 2 Like parts are designated by like characters throughout.

A is the headlight casing having the enlarged forward portion A within whlch the reflector and lighting element are mounted The front of the headlight casing is closed by a hinged door B. The rear of the casing is preferably closed as shown and has downwardly depending therefrom a lug G whlch is provided with an enlarged opening C. Downwardly and rearwardly extending from the enlarged portion of the casing are a pair of supporting lugs D, D which are perforated and have mounted within them a shaft D upon either end of which is mounted a nut D D I v Beneath the casing and arranged for en-: gagement with the top of the locomotive or more particularly with a bracket fastened on the top of the locomotive is a supporting frame E provided with a plurality of attaching feet E, E. This member E has two substantially vertical sides as shown. In. one of these sides'is a slot E and 0 p0- site it in the-other end is around peraration. For some purposes slots may be used in both sides, of the member E. The shaft D extends through the slots or slotted perforation and by means of it the casing is pivotally supported at its forward end by the member E.

Projecting rcarwardly from the frame E is a member 'F in which there is screw threaded a locking screw G which has mountedupon it a washer G. Spaced latcrally from the screw G and screw threaded also in the part Fis a vertical adjusting screw H provided with a locking nut H.

As shown the screw G lies within the large perforation C and when it is ti htened the washer G bears against the lug Ci, thus holding the casing in place.

Located within the headlight is any suitable light source not here shown as it forms no part of the present invention. There is also located within the casing a reflector I held in position in any suitable manner, and the front-door B has located within it a transparent glass covering B which is held in position in the door by B means of packing The sides of the casing are provided with doors J, each of which has a transparent panel J. The doors provided with adjustable locking means J adjacent their bottom.

The door B is hinged at B as shown and is provided on its opposite side with a looking latch. The latch is composed of a handleK whiclris pivoted on the door at K and provided with an npperextension K and a hook shaped locking'and engaging member K This member engages a pin L on the casing. Pivoted upon this pin is a locking dog M. This dog is providedon its inner face with an inwardly extending projection M adapted when in the locking position to contact the lower face of the hook K and adapted when it is desired to open the latch to be swung up out of the engaging position. Although I have shown an operative device, still it will be obvious that many changes in size, shape and arrangement of parts may be made without departing materially from the spirit of my invention, and I wish therefore that my showingbe taken as in a sense diagrammatic.

' of the latch is dee upperextension K signed to act as a lever when the latch is face of the extension K bears against the pin L with a wedge action and forces the door outward and open.

. The use and operation of my invention and vertical adjustment is made by rotation of the adjusting screw at the rear of the casing. When such adjustment is completed the locking screw is loosened and the requisite raising or rear of the casing manipulating the elevating screw, and the locking screw is then tightened andthe parts are held in position. -For right and left adjustment, however. an additional is accomplished by means has been provided. The shaft upon which the forward end of the casing is pivoted can itself be somewhat moved. Thus if there be two slots, one in either side of the supporting frame as suggested above, the supporting shaft may be moved forward in one of these slots and rearward in the other,

and thus the headlight will be shifted so as to bend to one side or the other to correspond to the direction of movement. For some purposes it is suflicient to have one slot within which the supporting shaft lies and to have at the other end a perforation corresponding in size to the shaft. This perforation permits sufficient play so that the other end of the shaft maybe moved forward or back, and thus the casing may be moved so as to point either to the right or to the left.

In case of adjustment either laterally or vertically the rear holding screw is loosened to accomplish the adjustment and is then tightened to hold the parts in the desired position.

When the parts of the latch are as shown in Figure 1 the latclr'ca-nno't he accidentally opened nor'can it be opened by mere manipulation of the handle. It is necessary to swing the locking dog up so that it can no longer engage the hook of the latch, then the latch handle may be rotated so as to bring the latch out of engagementand per:

mit opening of the door.-

I claim:

1. In combination in a locomotive light, a light casing and a supporting bed upon which it is mounted and means for adjusting the casing vertically and laterally with relation to said bed,'said means including slots in the side of' and adjacent the forwardend of said bed, and lugs on said caslowering of the ing -adapted to be supported from said slots to permit vertical pivotal movement of the casingwith relationto the bed and adapted I to be moved lengthwise from said slots to permit lateral rotation of the casing.

2. In combination in a locomotive light, a

light casing and a supporting bed upon which it is mounted and means for adjusting the casing vertically and laterally with relation to said bed. said means including slots in said bed and lugs on said casing adapted to be supported from said slots to permit pivotal movement of the casing with relation to the bed and adapted to be moved lengthwise along said slots to perm't lateral rotation of the casing, and an additional locking lug on said casing and a lug on said bed and means for securing the two together in a plurality of adjusted positions.

3. In combination in a locomotive light,

, tion between said bed and said casing, the

pivot points of said connection adapted to be shifted in a generally horizontal plane and a connection in-the rear of said casing for locking the same in adjusted position with relation to said bed.

5. In combination in a a light casing and a supporting bed upon .which it is mounted, the bed provided wth a pair of slots adjacent its forward end and the casing provided with a pair of lugs adjacent its forward end adapted to form pivotal support for the casing from said slots, the casing provided with a lug in its rear and the bed responding lug and'the two adapted tov be locked together in a plurality of adjustedpositions.

6. In combination in a locomotive light, a light casing and a supporting bed upon which it is mounted and means for relatively adjusting the two, said means including slots adjacent the lugs adjacent the forward end of said casing adapted pivotally to support the casing from said slots, a lug in the rear of said bed rovided with an adjusting screw adapte to raise and lower the rear of said casing with relation to said bed, 2. lug in the rear of locomotive light,
